retrieve data from database in for loop - codeigniter

Question

my controller is
function shiftstudentdetailsmultiple(){
$data['Show'] = $this->input->post('show[]');
$roll = $this->input->post('roll[]');
//echo sizeof($data1);
for($i=0;$i<sizeof($roll);$i++)
{
$data['results'] = $this->FetchData->getstudentsdetailscouseandmultiple($roll[$i]);
}
$this->load->view('registrar/shift_student_view', $data);
}
and model is
function getstudentsdetailscouseandmultiple($Uniq_Id){
$this->db->select("sprd.Uniq_Id, sprd.Name, sprd.Uni_Roll_No, cd.Course_Name, bd.Branch_Name, sprd.Year, sprd.Session, sprd.Section, sprd.Fee_Status, sprd.Curr_Status");
$this->db->where("sprd.Uniq_Id",$Uniq_Id);
$this->db->from("Students_Prim_Detals sprd");
$this->db->join('Course_Details cd', 'cd.Course_Id=sprd.Course_id');
$this->db->join('Branch_Details bd', 'bd.Branch_Id=sprd.Branch_id');
$query = $this->db->get();
if ($query->num_rows() > 0){
return $query->result();
}
else {
return false;
}
}
when showing in view the fetching data showing only one time.. but in my database i have more then 4 entry when i print_r
$data['results']=this->FetchData->getstudentsdetailscouseandmultiple($roll[$i]);
the data showing correct .. when load only showing one data..the last entry..
$this->load->view('registrar/shift_student_view', $data);

Each time you call...
$data['results'] = $this->FetchData->getstudentsdetailscouseandmultiple($roll[$i]);
you replace the value stored in $data['results'] with the new return. So only one return is sent to the view.
You will need to revise your controller along these lines.
$student_detail = array();
for($i=0;$i<sizeof($roll);$i++)
{
$student_detail[] = $this->FetchData->getstudentsdetailscouseandmultiple($roll[$i]);
}
$data['results'] = $student_detail;
Then in your view you will have to loop through $results to display each item in the array.
foreach($results as $detail){
echo "Name: ". $detail->name;
echo "Course: ". $detail->Course_Name;
//etc...
}
